Aliens, Gods and Heroes (S03E15)

Superhuman strength... Supernatural powers... And the awesome ability to fly. Throughout history, mankind has told incredible tales of gods with extraordinary powers. But are these accounts merely tall tales, or could they be based on factual events? If mythical gods really did exist, were they, as ancient astronaut theorists believe, extraterrestrial beings? Could man's desire to be faster, stronger, and even to ascend to the stars be an attempt to recreate advanced technology witnessed in the ancient past? Or could the desire for otherworldly powers be implanted in our DNA? Could this help to explain the enormous and enduring popularity of gods, titans and other so-called "super-heroes"? (iTunes)
